Can't enable RST, but already in RAID.

Hi, I've a problem that I can't solve alone.
After a lot of problems I found the way to set in RAID mode my SSD (Samsung 830 64GB) and my primary HD (Seagate Barracuda 1TB).
The Hard Drive is partitioned in two, one little partition to the system, the other one for documents and programs. That's a sort of protection for my important files.
The problem is that in the Intel Rapid Storage software, I can't find the way to enable SSD caching.
Here's how I view the program. How you can see I can't se the "Accelerate" tab...

I have an Asrock Z68 Extreme4 Gen3, and another 640GB HD, connected on the Marvell SATA port, in AHCI mode.

That's not SSD caching, that's just the write back cache that write to memory first then to the drive shortly after. It's to give the appearance of faster write speeds. If you want to use an SSD as a cache for a physical drive, I thought you needed to be running your drives in AHCI to do that.

I apparently misunderstood what the OP was trying to achieve, thanks for the clarification.

And is the IRST write caching not the same as what AsRock posted (Enable write caching), or am I misinterpreting it?

EDIT: Wait, you said that your setup is in AHCI? RST requires RAID for its operation. You'll likely need a full re-install.

If that's the case do this:
1. Connect just the main drive, forget the SSD for now.
2. Set HDD to RAID on bios
3. Install Windows normally, update, install drivers, etc.
4. Turn off the PC and connect the SSD.
5. Enable RST on bios
6. You must now see a RAID setup screen just before your bios loads, if you want you can set the acceleration there by pressing CTRl-I.
7. Install the latest RST software from Intel.

Yeah, I've this error: "there are no accelerated disks/volumes to display"
I read online that I can change the link of my SATA ports to solve the problem... One guy when linked SSD and HD through SATA2 ports, solved the problem. But Samsung 830 is a SATA3.
Maybe I've to connect the Seagate Barracuda through a SATA2 port.

I'm on windows 8. I don't think the problem is in the is or drivers. I think that because also in optrom I can't enable it. It seems a BIOS problem.... Maybe the option is hidden like a ninja.
What motherboard do you have? If you have the my same one, you can help me with uefi settings.
